Hello! I have a 4Gb flash-card with FAT32 filesystem. Whenever I try to mount it (on 5.x and 4.x) I get: msdos: /dev/da0s1: Invalid argument and the kernel complains: da0: reading primary partition table: error reading fsbn 0 mountmsdosfs(): bad FAT32 filesystem The method works with smaller cards in the same card-reader. This card works fine inside the camera, and I can get the pictures via. PTP protocol using gphoto. Fdisk da0 says: ******* Working on device /dev/da0 ******* parameters extracted from in-core disklabel are: cylinders=7936 heads=16 sectors/track=63 (1008 blks/cyl) Figures below won't work with BIOS for partitions not in cyl 1 parameters to be used for BIOS calculations are: cylinders=7936 heads=16 sectors/track=63 (1008 blks/cyl) Media sector size is 512 Warning: BIOS sector numbering starts with sector 1 Information from DOS bootblock is: The data for partition 1 is: sysid 12,(DOS or Windows 95 with 32 bit FAT, LBA) start 63, size 7998417 (3905 Meg), flag 80 (active) beg: cyl 0/ head 1/ sector 1; end: cyl 766/ head 15/ sector 63 The data for partition 2 is: <UNUSED> The data for partition 3 is: <UNUSED> The data for partition 4 is: <UNUSED> Disklabel da0 says: # /dev/da0: type: SCSI disk: SanDisk label: ImageMate II flags: bytes/sector: 512 sectors/track: 63 tracks/cylinder: 16 sectors/cylinder: 1008 cylinders: 7936 sectors/unit: 7999489 rpm: 3600 interleave: 1 trackskew: 0 cylinderskew: 0 headswitch: 0 # milliseconds track-to-track seek: 0 # milliseconds drivedata: 0 8 partitions: # size offset fstype [fsize bsize bps/cpg] c: 7999489 0 unused 0 0 # (Cyl. 0 - 7936*) Looks like OpenBSD discussed something similar 5 years ago: http://monkey.org/openbsd/archive/tech/0002/msg00167.html Any suggestions? I really hate using PTP via the camera to transfer pictures from this device, and I'd like to be able to store other things there in addition to pictures. Thanks! -mi
